This is a criminal matter, a Class 1 Misdemeanor. You can receive, as a maximum punishment, one year in jail and/or a $2,500 fine. For a first offense, active incarceration is often not imposed. You need to consult a criminal defense attorney as soon as you can. With regard to the letter that you will possibly receive, you can talk with the attorney that sends you the letter or consult with a local attorney to represent your interests.
Please remember that if you find an answer particularly helpful, please mark it as helpful or "best answer" so that the attorneys who volunteer their time to answer these questions have feedback. This answer is only for informational purposes, is not legal advice, and does not create an attorney-client relationship. Every case is different and must be judged on its own unique facts.
If you are found guilty or if you plead guilty, it will stay on your record forever. It will stay on you record even if you are found not guilty, unless you get it expunged. It is important to try and remember everything so you can give your lawyer all of the facts. Please do not post any more information about the case online (as this is a public forum); I highly encourage you to call a criminal lawyer as soon as possible, so that you can receive a consultation privately.
